The same high-performance packing materials utilized in the production of all Waters analytical columns are also employed in the Symmetry C18 Sentry Guard Cartridge. It has been created and constructed in particular for circumstances when a greater capacity for biological fluid cleansing and/or temperature control is required.

Utilize the Sentry Guard Cartridge for Symmetry C18 to extend column longevity. A piece of safety lab equipment called a guard cartridge is positioned in between the injector and the analytical column. It works by preventing suspended particles and chemical contaminants from entering the analytical column.

Invest in the LCGC Certified Clear Glass 12 x 32 mm Screw Neck Vial, with Cap and Preslit PTFE/Silicone Septum, 2 mL Volume, 100/pk so you can store your analytes in an inert storage with the confidence that there will be no interference with them. These vials are made to meet the requirements of LC/GC certification and to take into account all aspects of use, including volatility, tray design, and needle design. A HPLC test is performed on every vial to check for traces of compounds introduced during processing and manufacture.

These vials have PTFE chemical resistance up until rupture, at which point the silicone chemical compatibility of the septum kicks in. This permits operating temperatures between -40 C and 200 C.
